For this purpose, the artificial control of the magnetic anisotropy of ferromagnetic materials is of great importance. Here, we demonstrate the control of the carrier-energy dependence of the magnetic anisotropy of the density of states (DOS) using the quantum size effect in a single-crystal ferromagnetic material, GaMnAs. We show that the mainly twofold symmetry of the magnetic anisotropy of DOS, which is attributed to the impurity band, is changed to a fourfold symmetry by enhancing the quantum size effect in the valence band of the GaMnAs quantum wells. By combination with the gate electric-field control technique, our concept of the usage of the quantum size effect for the control of the magnetism will pave the way for the ultra-low-power manipulation of magnetization in future spintronic devices.","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"UTokyo Research掲載「磁性をデザインする新たな手法を開拓」 URI: http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/pioneering-new-methods-for-designing-magnetism.html","subitem_description_type":"Other"},{"subitem_description":"UTokyo Research \"Pioneering new methods for designing magnetism\" URI: http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/pioneering-new-methods-for-designing-magnetism.html","subitem_description_type":"Other"}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Nature"}]},"item_2_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1038/ncomms15387","subitem_relation_type_select":"DOI"}}]},"item_2_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type":"isReferencedBy","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.u-tokyo.ac.jp/focus/ja/articles/a_00574.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type":"isReferencedBy","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.u-tokyo.ac.jp/focus/en/articles/a_00558.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1038/ncomms15387","subitem_relation_type_select":"DOI"}}]},"item_2_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© The Author(s) 2017.
